lowing conditions may prevent the
main beam headlight control from turning off
the headlights in time or from turning off al-
together:
● In poorly lit towns with highly reflective
signs.
● Other in
sufficiently lit road users (such as
pedestri
ans or cyclists). ●
On tight bends
and steep slopes (bumps)
and when oncoming vehicles are partially ob-
scured.
● When the drivers of other oncoming vehi-
cle
s (such as a truck) can see over a guard
rail in the centre of the road.
● If the camera is damaged or the power sup-
ply i
s cut off.
● In fog, snow and heavy rain.
● With dust and sand turbulence.
● With loose gravel in the field of vision of
the camera.
● When the fiel
d of vision of the camera is
mist
ed up, dirty or covered by stickers, snow,
ice, etc. WARNING
The convenience features of the main beam
as s
ist should not encourage the taking of
risks. The system is not a replacement for
driver concentration.
● You are always in control of the main beam
and adaptin
g it to the light, visibility and traf-

● It is possible that the main beam headlight
contro
l does not recognise all driving situa-
tions and is limited under certain circumstan-

The hazard warning lights are used to draw
the attention of other road users to your vehi-
cle in emergencies.
If your vehicle breaks down:
1. Park your vehicle at a safe distance from movin
g traffic.
2. Press the button to switch on the hazard warning lights
››› .
3. Switch the ignition off.
4. Apply the handbrake.
5. For a manual gearbox, engage 1st gear; for an aut
om
atic gearbox, move the gear
lever to P. 6. Use the warning triangle to draw the atten-
tion of other ro
ad users to your vehicle.
7. Always take the vehicle key with you when you le
ave the vehicle.
All turn signals flash simultaneously when
the hazard warning lights are switched on.
The two turn signal turn signal lamps
and the turn signal lamp in the switch will
flash at the same time. The simultaneous
hazard warning lights also work when the ig-
nition is switched off.
Emergency braking warning
If the vehicle brakes suddenly and continu-
ously at a speed of more than 80 km/h (50
mph), the brake light flashes several times
per second to warn the vehicles driving be-
hind. If you continue braking, the hazard
warning lights will come on automatically
when the vehicle comes to a standstill. They
switch off automatically when the vehicle
starts to move again. WARNING
● The risk of
an accident increases if your ve-
hicle breaks down. Always use the hazard
warning lights and a warning triangle to draw
the attention of other road users to your sta-
tionary vehicle.
● Due to the high temperatures that the cata-
lytic con
verter can reach, never park in an
area where the catalytic converter could come into contact with highly inflammable materi-
al
s, f
or example dry grass or spilt petrol. This
could start a fire. Note
● The b atter
y will run down if the hazard
warning lights are left on for a long time,
even if the ignition is switched off.
● The use of the hazard warning lights de-
scribed her
e is subject to the relevant statu-
tory requirements. Parking lights
When the parking light is switched on, (right

Driving
The handbrake should be applied firmly to
pr ev
ent
the vehicle from accidentally rolling
away.
Always apply the handbrake when you leave
your vehicle and when you park.
Applying the handbrake
– Pull the handbrake lever up firmly
›››
Fig. 196.
Releasing the handbrake
– Pull the lever up slightly and press the re-
lea
se knob in the direction of the arrow
››› Fig. 196 and guide the handbrake lever
down fully ››› .
A lw
a
ys pull the handbrake all the way up, so
there is less risk of driving off with it still en-
gaged ››› .
The h andbr
ak
e warning lamp lights up
when the handbrake is applied and the igni-
tion switched on. The warning lamp turns off
when the handbrake is released.
If you drive faster than 6 km/h (4 mph) with
the handbrake on, the following message*
will appear on the instrument panel: HAND-
BRAKE ON. You will also hear an audible
warning. WARNING
● Never u se the h
andbrake to stop the vehi-
cle when it is in motion. The braking distance is considerably longer, because braking is
only
ap
plied to the rear wheels. Risk of acci-
dent!
● If the handbrake is only partially released,
this w
ill cause the rear brakes to overheat,
which can impair the function of the brake
system and could lead to an accident. This al-
so causes premature wear on the rear brake
pads. CAUTION
Always apply the handbrake before you leave
the vehic
le. Put it in 1st gear as well. Parking
The handbrake should always be firmly ap-
p
lied when the
v
ehicle is parked.
Always note the following points when park-
ing the vehicle: – Use the brake pedal to stop the vehicle.
– Apply the handbrake.
– Put it in 1st gear.
– Switch the engine off and remove the key
from the ignition. T
urn the steering wheel
slightly to engage the steering lock.
– Never leave a vehicle key in the vehicle. Additional notes on parking the vehicle on
gradient
s:
Turn the steering wheel so that the vehicle
rolls against the kerb if it started to roll.
● If the vehicle is parked facing downhil
l,
turn the front wheels so that they point to-
wards the kerb .
● If the vehicle is parked facing uphill
, turn
the front wheels so that they point away from
the kerb.
● Secure the vehicle as usual by applying the
handbrak
e firmly and putting it in 1st gear. WARNING
● Tak e me
asures to reduce the risk of injury
when you leave your vehicle unattended.
● Never park where the hot exhaust system
coul
d ignite inflammable materials, such as
dry grass, low bushes, spilt fuel etc.
● Never allow vehicle occupants to remain in
the vehic
le when it is locked. They would be
unable to open the vehicle from the inside,
and could become trapped in the vehicle in
an emergency. In the event of an emergency,
locked doors will delay assistance to vehicle
occupants.
● Never leave children alone in the vehicle.

Operation
at a higher speed than the inner wheel. In
thi s
w
ay, the wheel that is turning faster (out-
er wheel) receives less drive torque than the
inner wheel. This may mean that in certain
situations the torque delivered to the inner
wheel is too high, causing the wheels to
spin. On the other hand, the outer wheel is
receiving a lower drive torque than it could
transmit. This causes an overall loss of lateral
grip on the front axle, resulting in understeer
or “lengthening” of the trajectory.
The XDS system can detect and correct this
effect via the sensors and signals of the ESC.
Via the ESC, the XDS will brake the inside
wheel and counter the excess driving torque
of that wheel. This means that the driver's
desired trajectory is much more precise.
The XDS system works in combination with
the ESC and is always active, even when ASR
traction control is disconnected, or the ESC in
Sport mode or disconnected.
Multi-collision Brake
In an accident, the multi-collision brake can
help the driver by braking to avoid the risk of
skidding during the accident, which could
lead to further collisions.
The multi-collision brake works for front, side
or rear accidents, when the airbag control
unit records its activation level and the acci-
dent takes place at a speed of over 10 km/h
(6 mph). The ESC automatically brakes the vehicle, as long as the accident has not dam-
aged the ESC, the br
ake hydraulics or the on-
board network
The following actions control automatic brak-
ing during the accident:
● When the driver presses the accelerator,
the automatic
braking does not take place.
● When the braking pressure through press-
ing the brak
e pedal is greater than the sys-
tem’s braking pressure the vehicle will brake
automatically.
● Multi-collision braking will not be available
if ESC
is malfunctioning. WARNING
● The ESC, ABS, ASR, EDL, el ectr
onic self-
locking differential or selective torque control
systems cannot exceed the limits imposed by
the laws of physics. Always bear this in mind,
especially on wet or slippery roads. If you no-
tice the systems cutting in, you should re-
duce your speed immediately to suit the road
and traffic conditions. Do not be encouraged
to take risks by the presence of more safety
systems. If you do, an accident may occur.
● Please remember that the accident risk al-
way
s increases if you drive fast, especially in
corners or on a slippery road, or if you follow
too close behind the vehicle in front of you.
The ESC, ABS, brake assist, EDL, electronic
self-locking and selective torque control sys-
tems cannot prevent accidents: risk of acci-
dents! ●
Ac c
elerate with caution on slippery surfa-
ces (for example, icy or snow-covered). De-
spite the control systems, the driven wheels
could spin, affecting the stability of the vehi-
cle: risk of accident! Note
● The ABS and ASR w i
ll only operate correctly
if the four wheels have identical tyres. Any
differences in the rolling radius of the tyres
can cause the system to reduce engine power
when this is not desired.
● The regulating processes of the systems
can mak
e noises when they intervene.
● If the warning lamp lights up
, or alter-
natively, there could be a fault ››› page 119. Switching on/off the ESC and ASR
